Rotator cuff repair surgery is often accompanied by pain of various degrees and duration. Severe postoperative pain can make it difficult for patient to fall asleep or even to lie down, which seriously affects the patient's satisfaction with the treatment. Previous studies have suggested that patients with chronic pain often have an anxiety state which aggravates the pain perception. Surgical patients all have different degrees of pain after surgery. Perioperative analgesia has always been the focus and hot spot , and the occurrence and severity of pain are affected by many factors, such as gender, surgical methods, emotional state, etc. Thus, assessing the factors that influence pain is the focus of the development of personalized analgesia programs. Objective To analyze the influence of preoperative factors on postoperative pain in patients after arthroscopic rotator cuff repair.

In this study, the patients with rotator cuff injuries admitted to the department of and orthopedics from January 2018 to December 2019 were included. Each patient was evaluated by visual analogue scale (VAS) , American Shoulder and elbow surgeons (ASES) , and self-rating anxiety scale (SAS) before surgery, and multiple linear regression was used to analyze the influencing factors of postoperative pain.

A total of 63 patients were included in the study. The average preoperative SAS score was (31.39±6.45) points. The average VAS scores of rest pain and motion pain were (1.26±1.17) points and (2.82±1.60) points respectively on the day after surgery. The average VAS scores of rest pain and motion pain were (1.11±1.18) points and (2.71±1.01) points respectively on the 1st day after surgery. The results of multiple linear regression analysis showed that preoperative SAS anxiety score was the independent influencing factor of rest pain and motion pain on the day after the operation, and motion pain on the 1st day after surgery (P<0.05) . In addition, analgesia method was also an independent factor affecting the motion pain on the 1st day after the operation (P<0.05) .

The preoperative anxiety state of patients with rotator cuff injury affects the postoperative pain response. The more severe anxiety state of patient was, the more intense the postoperative pain response would be. Preoperative assessment and intervention of patients’ anxiety state can help to diminish postoperative pain response, accelerate postoperative rehabilitation, and improve the quality of life.
